À propos de ce service
Stuck on a bug you can't crack? Send it to me I'll find the real cause and fix it properly, not with a band-aid.
I'm a full-stack developer who fixes bugs and errors in:
- React / Next.js hydration, state, rendering, UI issues
- Node.js / Express and Python / FastAPI backend, APIs, database
- TypeScript / JavaScript build and deployment errors
WHY TRUST ME
- 35+ bug fixes merged into major open-source projects: React Router, ESLint, Axios, Node.js and Jest. Finding the root cause in an unfamiliar codebase is literally my main skill.
- On a recent client platform I found a billing bug that would have charged every customer 100x the correct amount fixed across their frontend and backend, delivered three days early.
- I built and maintain an AI-powered platform, "NSU InSights" used by 4,000+ students, solo.
WHAT YOU GET
- The bug fixed and fully tested
- A clear explanation of what actually caused it
- Clean code that matches your existing style
HOW IT WORKS
Message me your repo or code and what's broken screenshots or error logs help. I'll confirm the scope and timeline in writing before you order.

Hi, I’m Mahin — a full-stack developer with 2 years of experience and a CSE background from North South University.
I build modern, reliable web apps using React, Next.js, Node.js, Python/FastAPI, PostgreSQL, and MongoDB. I created NSU Insights, my own AI platform used by 4,000+ students. I specialize in solving complex bugs, finding root causes, and delivering clean, production-ready solutions. I’ve also contributed fixes to 35+ open-source projects including React Router, ESLint, Axios, Node.js, and Jest.
Have a project or tricky bug? Send me the details — I’ll handle it.

FAQ
What do you need from me to get started?
Your code or repo access, a clear description of the bug, and steps to reproduce it. Screenshots, error messages, or console logs help me find the cause much faster.
What if you can't fix my bug?
I'll always be honest upfront. If I investigate and genuinely can't solve it, you get a full refund. But finding the root cause in unfamiliar code is my main skill — most bugs are very fixable.
Is my code safe and kept confidential?
Absolutely. Your code and data stay completely private, and I'm happy to sign an NDA if you need one.
I'm not sure which package fits my issue — what should I do?
Just message me first with the details. I'll review the bug, tell you honestly what it'll take, and recommend the right package. No surprises.
Can you also add features or build new pages, not just fix bugs?
Yes — I'm a full-stack developer (React, Next.js, Node, FastAPI). If you need new features or a full app, message me and I'll set up a custom offer.
